HURRICANE INFORMATION:
The hurricane season extends from June 1st through November 30th. Hurricanes can cause excessive damage to vessels and loss of life. To minimize these dangers, the following precautions should be taken by all mariners before getting underway during the hurricane season:
(a) Instruction of crew and passengers in location of emergency equipment and emergency procedures;
(b) Pre-sailing check of vessel, machinery, and equipment for seaworthiness;
(c) Installation of strong ground tackle;
(d) Review of storm center evasion procedures;
(e) Knowledge of nearest hurricane shelter or port; and
(f) Constant radio watches on channel 16 VHF-FM and frequent monitoring of weather broadcasts.
The civilian hurricane warning service for the North Atlantic is provided by the National Hurricane Center, Miami, Florida. The center collates ship, aircraft, radar, and satellite data to produce and issue tropical cyclone warnings and forecasts for the North Atlantic Ocean, including the Caribbean Sea and the Gulf of Mexico. A Tropical Cyclone Public Advisory (TCP) is issued every six hours, with intermediate bulletins provided as needed. For tropical storms and hurricanes threatening to cross the coast of the U.S., coastal warnings are issued to the public so that precautionary actions, including evacuation, can be initiated to minimize damage and loss of life.
Four alerts are issued:
(a) TROPICAL STORM WATCH – An announcement that sustained winds of 34 to 63 knots (39 to 73 mph or 63 to 118 km/hr) are possible within the specified area within 48 hours in association with a tropical, subtropical, or post-tropical cyclone.
(b) TROPICAL STORM WARNING – An announcement that sustained winds of 34 to 63 knots (39 to 73 mph or 63 to 118 km/hr) are expected somewhere within the specified area within 36 hours in association with a tropical, subtropical, or post-tropical cyclone.
(c) HURRICANE WATCH – An announcement that sustained winds of 64 knots (74 mph or 119 km/hr) or higher are possible within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical storm force winds.
(d) HURRICANE WARNING – An announcement that sustained winds of 64 knots (74 mph or 119 km/hr) or higher are expected somewhere within the specified area in association with a tropical, subtropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds. The warning can remain in effect when dangerously high water or a combination of dangerously high water and waves continue, even though winds may be less than hurricane force.

HURRICANE INFORMATION CONT:
Additional information of interest to mariners is included in the Tropical Cyclone Forecast/Advisory (TCM) and the Tropical Cyclone Surface Wind Speed Probabilities (PWS) products. The TCM provides current and forecast storm positions, intensities, and wind fields out to 120 hours. The PWS provides probabilities of sustained wind speeds equal to or exceeding 34-, 50-, and 64-kt wind speed thresholds for select coastal and offshore locations
Mariners are reminded that aids to navigation, particularly lighted and unlighted buoys, may be moved from charted position, damaged, destroyed, extinguished, or otherwise deemed discrepant as a result of hurricanes and storms. Mariners should not rely solely upon the position or operation of an aid to navigation, but also employ such other methods of determining position as may be available. Port Hurricane Conditions are set up by the COTP and will change as the threat of severe weather increases, or as a storm approaches a specific COTP Area of Responsibility. For COTP-specific Port Hurricane Conditions, you should review information provided under the Port Directory tab of http://homeport.uscg.mil
Condition 4 – Hurricane Seasonal Alert. 01 June–30 November; port status: open.
Condition Whiskey – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 72 hours; port status: open.
Condition X-Ray – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 48 hours; port status: open.
Condition Yankee – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 24 hours; port status: restricted; vessel/facility control measures in effect.
Condition Zulu – Sustained Gale Force winds associated with Tropical Cyclone activity are predicted within 12 hours; port status: closed to all vessel traffic and waterside activities except for activities approved by the COTP.
Drawbridges along the coast may deviate from normal operating procedures. Drawbridges are authorized to remain closed upon approach of Gale Force winds of 34 knots or greater. Extended closure periods may be authorized up to 8 hours prior to arrival of Gale Force winds to facilitate evacuation of land traffic. Due to the uncertainty of hurricane movements and bridge closures, mariners are urged to seek passage through drawbridges well in advance of the arrival of Gale Force winds.

Marine Safety Alert 02-24
Inspections and Compliance Directorate
DANGEROUS BYCATCH FROM DISCARDED MUNITIONS REMAINS A PRESENT DAY HAZARD
This Safety Alert is being issued to raise awareness of lurking hazards caused by discarded munitions, which often contain active explosives or chemical agents. Although the practice of dumping munitions into the sea ceased in 1970, a significant amount remains hidden in coastal waters, posing a safety hazard to commercial fisherman, dredge operators, and others who trawl and work the ocean floor.
Recently, a deckhand on a clamming vessel was severely burned when a canister was dredged up and brought onboard with clams and other debris. The canister likely contained mustard gas or another blistering agent, but did not display any obvious visual, audible, or odor indicators of discharging content. A member of the crew discovered the canister and threw it back overboard. Several hours later he developed a severe rash that required professional medical treatment.
Mustard gas is a chemical weapon developed during World War I. Millions of pounds of this product, other chemical weapons, bombs, torpedoes, artillery shells, and munitions were routinely disposed of and remain in U.S. coastal waters. Although many munition dump areas are well marked on navigation charts, numerous areas where munitions were discarded remain unmarked. There is also evidence suggesting that munitions were frequently “short dumped,” meaning dumped outside of the designated areas by contractors hired to take them to the intended locations.
The Coast Guard previously issued Safety Alert 11-16 and Safety Alert 6-10 on this same topic and continues to strongly recommend that persons involved in the fishing and dredging industries:
Review their navigational charts to ensure the areas in which they are trawling or dredging are not near labeled “Explosives Dumping Areas.” Such areas must be given wide berth and seafarers should recognize that surface bottoms change and that objects can move significant distances from their original disposal areas.
Review and follow recommendations from the Maritime Industry 3Rs Explosive Safety Guide.
Carefully record the position of any munitions encountered and returned to the sea.
Immediately report discovery to the National Response Center, at (800) 424-8802 to ensure a proper response and potential recovery. Alternatively, the local U.S. Coast Guard unit may be notified via VHF-FM Channel 16. This Safety Alert is provided for informational purposes only and does not relieve any domestic or international safety, operational, or material requirement. Developed by the Office of Commercial Vessel Compliance (CG-CVC) and distributed by the Office of Investigations and Casualty Analysis (CG-INV). Questions may be submitted to HQS-SMB-CGINV@uscg.mil.
